I saw this on the Waco NBC news channel KCEN yesterday (5th)

Seven years ago a boy was batboy at a baseball game. Another player was taking practice swings when he lost his grip on the bat and it struck the boy in the chest causing his heart to stop. In the stands was a nurse and she rushed to the boys side and started CPR and brought the kid back.

Flash forward to November of last year.

A woman was at a local restarunt and started to choke. Her husband and a couple of other patrons tried the Heimlich maneuver on her with out success. The manager called one of the busboys whom he knew knew theHeimlich maneuver. The 17 year old came up performed the maneuver and dislodged the obstruction and saved the womans life.

Yep, as you guessed the teenager was the young boy that got hit with the bat and the woman was the lady that saved his life seven years ago. Now he saved her life. Neither at the time recognized the other, but after a brief chat they remembered each other.

talk about life coming full circle.
